A tower of ivory - The tower of ivory, the allusion being to some particular tower, built probably by Solomon 1 Kings 10:21.
Fishpools in Heshbon - Or, simply pools. Among the ruins to the south of Heshbon still remain a number of deep wells cut in the rock, and a large reservoir of water. The simile well sets forth the appearance of a large clear liquid eye (compare Song of Solomon 5:12 note).
Gate of Bath-rabbim - Perhaps the gate looking toward Rabbath-Ammon on the north side of the city, though this does not agree with the wells above mentioned; or, the gate of the city “full of people” Lamentations 1:1; or, an expression indicating the gate itself as the scene of numerous gatherings.
Nose - Better perhaps “face “or “brow.”
The tower of Lebanon - Possibly “the house of the forest of Lebanon” or part of it 1 Kings 7:2; 1 Kings 9:19, built by Solomon in the early part of his reign; or possibly a watchtower erected by David to overawe Damascus after his war with Hadadezer 2 Samuel 8:6.
